UNITED STATES PATENT oFF-Ion.

VVILLIAMARTHUR, OF NEVPORT, KENTUCKY.

IMPROVEMENT lN STEAM-GENERATORS.

Specification forming part of Letters Patent No. 104,533, dated June 2l, 1870.

\ I, VILLIAM ARTHUR, of Newport, Campbell coimty, Kentucky, have invented anew and useful Steam-Generator, of which the following is a specication:

Nature cmd Objects of the Intention.

General Description with reference to the Draw ing.

Figure l is a longitudinal section of a stealngenerator embodying my improvements. Fig. t 2 is a horizontal section of the same at the line X X. Fig. 3 is atransverse section of the same atthe line Y Y.

A may represent one or more customary return-flue horizontalboiler or boilers, snrmounted bythe usual steam-drum-B.

From the fire-place G, of any approved construction, the emanations of combustion are conducted over a bridge, D, into the ue E, which flue has a pit or depression, e, and communicates at its rear end, in the usual manner, with the return-flue F.

Extending athwart the flue E, at Aits depressed portion c, are one or more drums, G, into which-the feed-water is forced by means of one or more pipes,` H.

The drums G communicate, by ascending pipes I, with the boiler-bottom, and by descending pipes J with mud-receptacles K, of ordinary construction. v

Pipes L, leading from the ends of the drums G to the steam-chamber-B, enable the steam generated in the drums G to pass direct to said chamber, and thus facilitate the entrance of water into said drums, and promote circulation of Water in the boiler.

In the absence of a steam-drum, the pipes L may conduct directly into the top of the boiler.

Gages l may be attached to the side pipes, L, for the purpose of indicating the height ot' water in the boiler; or, if preferred, said pipes L may be located within theiue E, asV shown by dotted lines in Fig. 3, so as to stimulate the ascent of steam, and thereby promote circulation, and when the pipes L are thus v located the gages, if used, will, of course, be

secured to another part of the boiler.

The pipes I and J, being in line, permit the direct precipitation of mud from the boilers into the mnd-receivers.

Claims.

elements of the preceding claim, the. pipes L,

conducting steam from the drums G to the l steam-space of the boiler.

In testimony of which invention I hereunto set my hand.
